January 20"! 6'', 1842. Discovered some of the fibres of the Deelination thread broken and caught on the copper ring ; the fibres 

 were detached from the ring, but the thread broke away fibre by fibre during the remainder of the term. The observations before 6^. 

 are corrected by minus 13' in order to make the readings neai-ly as on other days, the difference being due to torsion force. These obser- 

 vations are given here ; they are not however considered of much, if of any value, as the fibres were probably breaking througliout the 

 whole term.
